increase the vibration and noise emissions over the total
working period.
To estimate vibration and noise emissions accurately, the
times when the tool is switched off or when it is running but
not actually being used should also be taken into account.
This may significantly reduce vibration and noise emissions
over the total working period.
Implement additional safety measures to protect the oper-
ator from the effects of vibration, such as servicing the
power tool and application tools, keeping their hands warm,
and organising workflows correctly.
Assembly
u
Remove the battery from the power tool before carry-
ing out work on the power tool (e.g. maintenance,
changing tool, etc.). The battery should also be re-
moved for transport and storage.
There is risk of injury
from unintentionally pressing the on/off switch.
Battery Charging
u
Use only the chargers listed in the technical data.
Only
these chargers are matched to the lithium-ion battery of
your power tool.
Note:
The battery is supplied partially charged. To ensure
full battery capacity, fully charge the battery in the charger
before using your power tool for the first time.
The lithium-ion battery can be charged at any time without
reducing its service life. Interrupting the charging process
does not damage the battery.
The lithium-ion battery is protected against deep discharge
by the "Electronic Cell Protection (ECP)". When the battery
is discharged, the power tool is switched off by means of a
protective circuit: The application tool no longer rotates.
u
Do not continue to press the On/Off switch after the
power tool has automatically switched off.
The battery
can be damaged.
Removing the Battery
The battery
(12)
is equipped with two locking levels to pre-
vent the battery from falling out when pushing the battery re-
lease button
(13)
unintentionally. As long as the battery is
inserted in the power tool, it is held in position by means of a
spring.
To remove the battery
(12)
, press the release button
(13)
and pull the battery out of the power tool.
Do not use force
to do this.
Battery charge indicator
The green LEDs on the battery charge indicator indicate the
state of charge of the battery. For safety reasons, it is only
possible to check the state of charge when the power tool is
not in operation.
Press the button for the battery charge indicator or
to
show the state of charge. This is also possible when the bat-
tery is removed.
If no LED lights up after pressing the button for the battery
charge indicator, then the battery is defective and must be
replaced.

Auxiliary handle
u
Do not operate your power tool without the auxiliary
handle
(4)
.
u
Before carrying out any work, make sure that the aux-
iliary handle is tightened.
Loss of control can cause per-
sonal injury.
Fitting the auxiliary handle
To open the auxiliary handle, turn the lower gripping end of
the auxiliary handle
(4)
in an anticlockwise direction.
Pull back the intermediate piece of the auxiliary handle
(5)
and hold it in this position.
Slide the auxiliary handle over the drill chuck to mount the
auxiliary handle on the power tool.
Then let go of the intermediate piece
(5)
.
Afterwards, turn the lower gripping end of the auxiliary
handle
(4)
clockwise to retighten it.
Swivelling the auxiliary handle
You can swivel the auxiliary handle
(4)
to any angle for a safe
work posture that minimises fatigue.
Turn the lower gripping end of the auxiliary handle
(4)
anti-
clockwise and swivel the auxiliary handle
(4)
into the re-
quired position. Afterwards, turn the lower gripping end of
the auxiliary handle
(4)
clockwise to retighten it.
Setting the drilling depth
You can use the depth stop
(3)
to set the required drilling
depth
